Bioburden encapsulated in spacecraft polymers (such as adhesives and coatings) poses a potential risk to jeopardize scientific exploration of other celestial bodies. This is particularly critical for spacecraft components intended for hard landing. So far, it remained unclear if polymers are indeed a source of microbial contamination. In addition, data with respect to survival of microbes durin...

Reports of molecular and cellular imaging using computed tomography (CT) are rapidly increasing. Many of these reports use gold nanoparticles. Bismuth has similar CT contrast properties to gold while being approximately 1000-fold less expensive. Herein we report the design, fabrication, characterization, and CT and fluorescence imaging properties of a novel, dual modality, fluorescent, polymer ...

The main objective of the research was to evaluate performance synbiotic delivery systems using pectin microgels on protection two probiotic strains (Lactobacillus casei ATCC 393 and Lactobacillus rhamnosus strain GG [ATCC 53103]) simulated gastrointestinal digestion (GD) storage conditions (4 ± 1 °C) in a 42 days trial. Microgel particles were prepared by ionotropic gelation method three varia...

Phytases are the largest group of feed enzymes increasing accessibility organic phosphorus for animals. Feed phytases usually sold as dried powder secreting producers, mainly micellar fungi. We proposed a new technology producing phytase from Obesumbacterium proteus (OPP) in yeast Yarrowia lipolytica cytosolic protein (encapsulated OPP), where capsule (yeast cell) protects enzyme unfavourable f...

Bacterial exopolysacchrides (EPSs) are produced by many bacteria. Nowadays there is an increasing interest in the isolation and exploitation of these polymers for industrial purposes. In general, biosynthesis of EPS varies from one strain to other strain and it depends on genes and enzymes involved in EPS production and secretion. In this study, EPS producing strains were isolated from municipa...

Based on the analysis of the structure of the double pinion electric power steering system(DP-EPS),the power steering system with induction motor DP-EPS is modeled and simulated by using the principle of dynamics. By vector control, the induction motor is equivalent to the form of DC motor, which reduces the complexity of EPS control, and lays the foundation for the follow-up control strategy r...

Enhanced Publications are a new way to publish scientific and other results in an electronic article. The advantage of EPs is that the relation between the article and the underlying data facilitate the peer review process and other quality assessment activities. Due to the link between de publication and the research data the publication can be much richer than a paper edition permits. We pres...

In this investigation, a nano-sized protein-encapsulated polymeric micelle was prepared by self-assembling human serum albumin (HSA) as a model protein and degradable block copolymer methoxy poly(ethylene glycol)-poly(β-amino ester) (PEG-PAE) with piperidine and imidazole rings. From the zeta potential measurement, the protein-encapsulated polymeric micelle showed a pH-tuning charge conversion ...

The use of liposomes in biological and medicinal sciences is a relatively new approach. The liposomal strategy greatly depends on the technological advancement in the formation of vesicles of various sizes and properties. In the current study, we encapsulated the venoms obtained from medically important scorpions such as Androctonus bicolor (AB), Androctonus crassicauda (AC), and Leiurus quinqu...
